Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] figure 1 It is an application environment diagram of a video coding system in an embodiment. like figure 1 As shown, the video coding system includes a server 110 and a terminal 120 . The server 110 can be used to obtain the video frame of the video; detect the moving target in the video frame, and determine the region where the moving target is located in the video frame as the region of interest; smooth the non-interest region that does not belong to the region of interest in the video frame After filtering, the video frame is encoded according to the encoding method in which the fideli...

Abstract

The invention relates to a video coding method and device. The method comprises the following steps: acquiring a video frame; detecting a moving target in the video frame, and determining a region in which the moving target is positioned as a region-of-interest in the video frame; and coding the video frame in a coding way that the fidelity of the region-of-interest is higher than the fidelity of a non-region-of-interest after smooth filtering of the non-region-of-interest not belonging to the region-of-interest in the video frame to obtain video code streams. Through adoption of the video coding method and device, relatively high picture quality can be kept in the region in which the moving target is positioned even for a video with a complex scene, and occupation of network resources by the coded video code streams is lowered by lowering of the fidelity of the non-region-of-interest.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video encoding method and device. Background technique [0002] Video is a data form involving dynamic images, and usually includes a series of video frames, and the dynamic images in the video can be displayed by playing the video frames continuously. Through video coding, a video format file can be converted into a video stream suitable for transmission by using a specific compression technology. [0003] The current video coding technology is suitable for the coding of video in normal scenes. However, for videos of some complex scenes, such as sports games or stage performances, due to various reasons such as violent video movement, rich details, and uneven lighting, it often leads to encoding problems. The image quality of the final video stream is difficult to control, or the encoded video stream occupies too much network resources to ensure the image qua...
